The wobble in that drill press is glorious

the "device" you're using is called a "TAP!

Well, first the trick of putting the round stock in the lath chuck this way is way too dangerous, next the flex of the workpiece and the tap is noticeably excessive, and the taper of the tap prevents it from fully engaging the workpiece all the way to the end. You can see from the Prussian blue the threads are not the same all the way. When he threads the nut on, it is really loose at the beginning and stops before it gets all the way to the end of the threads.

There are a couple of things working against him. He's trying to compensate for the taper on the tap by running it well beyond the end of the threads on the workpiece, but the workpiece still is winding up with a slight taper to the threads. I think a bigger problem is that the threads closest to the end of the workpiece are engaged the entire time the tool is cutting, while the threads on the end are waiting for the cutting tool to arrive. If it takes 12 revolutions of the spindle for a pass, the first thread will be cut 12 times _more_ than the last thread. Whereas with a single point tool, each thread is cut once for each pass.

Tiện ren như vậy thật là một ý tưởng điên thức tế chẳng có một thợ tiện nào làm như thế này cả

this is so stupid. Use a threading tool. If anyone thinks this is a good idea, they dont understand machining. The tap will flex further at the end and a thread mic will reveal that the pitch diameter is smaller on the end of the part as this tap flexes. Machinists have to make parts to a drawing so that it will fit other parts that are not in our possession. when cutting threads, we can not check with a nut or a bolt , we must check the pitch diameter with a pitch mic or a thread gage. some of these trick are fine if you are fixing Your tractor, but not for doing real work for customers who rely on Your parts fitting into mating components . Please understand threads and what the minimum and maximum tolerances are and once You do, You will not attempt these kinds of methods. We respect and love You guys, You are fellow metalworkers. Please up your game. It costs nothing and will make you so much better. Try using cutting oil for starters. Try indicating Your work instead of the wire method.

That's a total waste of time there is too much surface contact creating flexing and a very rough finish.Surely you would have a piece of HSS to sharpen a single point tool and cut the thread much faster and better finish.A little lubrication might help.BTW it is not a thread drill it's called a TAP.

Most of these guys demonstrating machining from parts of Indonesia don't understand what machining really is. Take mekanik messin from Indonesia; he is definitely not a machinist. Take a look at how he operates. His shop is also a "death trap." When you finish looking at mekanik messin take a look at Joe Pieczynski, Advanced Innovations, LLC. from Texas, U.S.A. The difference between the two is like night and day. I was a CNC machinist most of my life but I started out as an old-style machinist trained by, Germans brought over to the U.S.A. under "Operation Paperclip." I learned alot of fine machining techniques which I used in both my shop and later in life at a CNC shop.

Your lathe has screw cutting back gears so why not just cut the threads with a single point? If you really **must** do it this way, then turn the toolpost slightly so you don't get so much of a taper.

True, but if you want a non standard thread you won't find a die that will do it, say you want a 1" 20 TPI well you can use a 1/2 - 20 tap on a 1" dia piece of stock and get it done. Yes single point would be better if you have what you need to do it that way, but sometimes you don't have every tool needed

At 4.26 here is a good example of why this guy should have been making screws to hold the jaws to the vice . Here is a challenge for you as a apprentice toolmaker I saw a Russian Toolmaker win a bet when he cut a left hand thread into 12 mm thick plate using a Right hand tap . And yes it can be done I lost money betting it can't .

Your turn tool is above center

When he says manual Lathe I'm assuming it has no power feed or threading capability to sync the carriage with the spindle RPM. I get that but I don't get the need for stick-out here. He's using a Tap externally to do essentially what a Die does. Wouldn't it make more sense to support both ends of the tap? Doing it like this is begging for a broken Tap. The damn things will break when you do everything right. So, there's no need to invite it! vandalsgarge commented about the Tap's taper and how it will effect the depth of the threads. He's correct but the tapered nature of this type of Tap isn't even needed in this operation. Wakodahatchee Chris

Clearly didn't work as the nut got stuck halfway up the threads. This is because the method shown requires synchronizing the rotational speed of the lathe with the linear speed you move the tap to get the right thread pitch, which manually, is virtually impossible, and certainly can't be done that way with precision. This is why you buy a die of the right size. Lots of work and wasted material to get a complete lack of precision, resulting in failure.

@hf-lz2qw

Жыл бұрын

I question your response and in a polite quizitive way....On my LeBlond lathe, when I chuck in my thread cutting tool on my tool post, it is no different than the videos tap....just as long as the thread pitch per diameter of the work is the same, its just that the video is capable of having more "teeth of the tap" cutters in a row instead of single. When I cut threads, I can slow or speed up my chuck ( rotational ) speed per type and size of material I want to thread. Example: If I want to cut 1/2" -13 ( nc ) threads, I set my carriage speed for that thread pitch, so the carriage is going to move the same speed regardless of what is in the toolpost ( tap or thread cutting toolholder ). IF my chuck spins faster, then my carriage runs faster too, but still in the same ratio to retain that 13 pitch. Also look up Vardex threading inserts. These are actually doing the same thing as the tap is, only the inserts are mounted in a toolholder, similar like inserts for an indexable endmill or facemill. I think the reason the nut did not go on the full way is either : 1.) the tap was not positioned perfectly parallel to the stock or 2.) another pass should have been made to "clean up" the threads, or 3.) he did not have the O.D. cut down enough.... or 4. ) the chuck is not dead centered ( meaning the shaft is "camming" ) or he has spindle and bearing wear or 5.) the tap is worn . I'll agree, that a die would probably make up for these errors especially in concentricity, but this is not a bad idea to try if a guy was in a pickle and did not have any special tooling on hand, and had to make do with what he had say for like a "meatball surgery one up fix on a late night or weekend". I would not do any "production" work this way.

@chargehanger

the nut got stuck because the thread is not finished. The second half did not see the end of the tap, you still see blue ink there.. The tap is conical, and to finish the piece, you'll have to pass the whole length, which is impossible with this workpiece.

I appreciate your experiment but it's obvious too many things went wrong.

But...WHY, he seem to have a thread''feed''on that lathe anyway. Why not just use a 60 degree insert or grind a HSS ??????????
